1 Claim. (Cl. 131-225) The present invention relates to a cigar or cigarette holder and more particularly to a filter holder constructed in the form of a sealed unit which minimizes or greatly reduces the health hazard involved by smoking tobacco.

The sealed-unit holder according to the invention comprises a long unitary tube tapering to a mouthpiece at one end and having a cylindrical opposite end for the reception of a sealing cap fitted thereinto and provided with a capsular portion disposed in and sealed to the tube which is filled with a mass of filtering granules between the mouthpiece and the capsular portion to provide a long detoxifying passage for smoke passing from the cigar or cigarette to the mouth of the smoker.

Such construction offers important advantages in simplicity, economy and efliciency and also provides a holder which does not show soil or use and which eliminates cleaning and refilling.

An object of the invention is to provide a filter which i is adequate to remove nicotine, tars and toxic gases from the smoke passing to the smokers mouth.

Another object of the invention is to provide a filter holder operating in an efficient manner and wherein the wall of the tube constitutes the direct container for the filtering granules through which the smoke must pass via the channels between the granules.

A further object resides in the provision of an inexpensive filter holder which may be used for a limited number of cigarettes and then discarded.

Other objects and advantages will be appreciated by those skilled in the art or will be understood from the following description.

In the accompanying drawings:

Fig. 1 is a longitudinal section of one embodiment of the invention with the sealing cap disassembled;

Fig. 2 is a longitudinal section of the holder of Fig. 1 with the sealing cap in position ready for the filter to be used;

Fig. 3 is an end view looking from right to left of Fig. 2;

Fig. 4 is a longitudinal section of a modified form of the invention wherein the tube and sealing cap are provided with interfitting and interlocking teeth and indentatious and with the sealing cap disassembled;

Fig. 5 is a longtiudinal section of the embodiment of Fig. 4 with the sealing cap in assembled position;

Fig. 6 is a sectional view taken on line 6-6 of Fig. 5;

Fig. 7 is a fragmentary longitudinal section of a further form of the invention wherein the sealing cap is provided with grooves to receive a sealant and prevent relative rotation of the tube and cap when assembled and sealed;

Fig. 8 is a sectional view taken on line 8-8 of Fig. 7 on a slightly larger scale, looking leftwardly;

Fig. 9 shows, in fragmentary longtiudinal section, the assembled tube and cap of Fig. 7;

Fig. 10 is a view similar to Fig. 7 of a further modified form of the invention wherein the tube and cap are serrated to provide a non-rotational locking interfit;

Fig. 11 is a section taken on line 11-11 of Fig. 10;

Fig. 12 is a section taken on line 12-12 of Fig. 10;

Fig. 13 shows, in fragmentary longitudinal section, the assembled tube and cap of Fig. 10; and

Fig. 14 is a section taken on line l414 of Fig. 13.

Referring to the drawings in detail, a filter holder in accordance with the invention comprises a long unitary tapering tube a and a sealing cap b. Both the tube and the cap are made of synthetic plastics, the tube being preferably made of polyethylene and the cap from a Bakelitetype resin, but other plastics may be used. The tube a has a mouthpiece 2 at one end, which is provided with a central aperture 3 through which smoke passes to the smokers mouth. The other end of the tube is cylindrical, as shown at 4, so that the filtering granules 1 may be easily loaded thereinto. As will be observed, the filtering granules come in direct contact with the inner surface of the tube and substantially completely fill the tube, which acts as a direct container for the filtering granules.

Sealing cap b has a cylindrical end 6 with a cavity 7 for the reception of one end of a cigar or cigarette and beyond the cylindrical portion the cap is provided with a reduced capsular portion 5 which has an opening 8 centrally of the closed end thereof and which opening 8 is preferably cruciform but may be of other shapes.

The construction of the cap is described provides a step at the juncture of the cylindrical portion and the capsular portion, which step abuts against the cylindrical edge of the tube when the cap is assembled with the tube as shown in Fig. 2. The cylindrical portion of the cap is of the same size as the cylindrical end of the tube so that when the two are assembled the cylindrical portion of the cap forms a smooth and flush continuation of the tube.

The filtering granules 1. are preferably composed of carbon and silica gel and the individual granules are of such size that they are incapable of passing through either of the openings 3 or 8 so that the filtering granules are sealed in position and form a long tortuous path for smoke drawn by the smoker through the holder. The cap is further sealed in assembled position by means of any suitable adhesive, but when polyethylene is used for the tube, it has been found that the sealing can be effectively produced by using toluene, which is a solvent for polyethylene and which enables the cap and tube to be permanently assembled as a unit.

In the form of the invention shown in Figs. 1 to 3, the tube and capsular portion are smooth and free from surface irregularities whereas in the modified form of the invention shown in Figs. 4 to 6 the capsular portion is provided with a set of teeth 14 and the inner surface of the tube is provided with complementary notches or recesses 15. When this form of the invention is assembled, the resiliency of the materials enables the teeth to fit into the notches whereby the parts are held together against disassembly.

In the further modified form of the invention shown in Figs. 7 to 9, the capsular portion is provided with longitudinal grooves 9 which are adapted to receive the toluene and thus ensure a firm permanent connection without possibility of relative rotation of the cap and tube.

In a still further modified form of the invention as shown in Figs. 10 to 14, the capsular portion is serrated as shown at 13 and the tube is provided with complementary recesses 12 which, in conjunction with the sealing as by means of toluene, provides a firm permanent connection wherein the cap and tube cannot rotate relatively to one another. Thus, in this form of the invention, the capsule has parts 13 which enter the grooves or recesses 12 at a considerable number of points around the circumference.

The foregoing is intended as illustrative and not as limitative, since within the terms of the appended claim the details of construction may be additionally modified.

I claim:

In a cigarette or cigar holder having a long filter tube tapering at one end to a mouthpiece with an opening therethrough and having a cylindrical opposite end and a sealing cap for said opposite end, the construction wherein the sealing cap has a cylindrical body portion equal in diameter to the cylindrical end of the tube and forming a flush continuation thereof and a reduced capsular portion disposed within and sealed to the cylindrical 1 tube end and having a closed end provided with an opening communicating with the interior of the tube and external longitudinal grooves for the reception of sealing solvent, the annular step thus formed at the juncture of the reduced capsular portion and the cylindrical body portion abutting the cylindrical tube end.
